Teenagers are a special population for sexually transmitted infections (STIs). Due to some unique aspects of puberty and development, those under 25 are more likely to catch and transmit STIs. This is why testing recommendations may seem intense, but it’s only for your safety.

Here’s the rundown:

• If and when you start having sex it’s recommended that you have a blood test to check for HIV. In some regions of the United States it is also recommended to check for syphilis. 

• Females having vaginal sex should be tested for gonorrhea and chlamydia every year they are sexually actively. 

• Males who have sex with men should be tested for gonorrhea, chlamydia and syphilis every year they are sexually active. 

• If you are symptomatic, seek treatment as soon as possible. For females this might be vaginal itching, pain or discharge. For males this might be penile discharge or pain with urination.

• If you have sex with multiple partners or use IV drugs you should be checked more often than once a year.
